Retainers - keeping teeth straight for a lifetime
After successful completion of orthodontic treatment, teeth can move back to their old position. This is known as a relapse and may also be due to:
- growth
- pressure exerted by cheek, tongue, lip muscles
- side teeth moving forward
- eruption of wisdom teeth
Retainers are designed to keep your teeth in alignment long-term after orthodontic treatment.
They can be removable or fixed appliances.
Removable appliances usually only need to be worn at night.
